Measuring Distance Using Ultrasonic Sensor
INTRODUCTION
In this project I’m using an ultrasonic sensor that can precisely measure the distance to show how a beep sound come out when a car is reversed. You will noticed that when the car is too near to the barrier behind the car, it will give a continuous beep sound. Let’s figure out how it works!
